How to call them
Inside a dungeon, press Bots in the dungeon damage window, or type !bots in chat. Pick the classes you want in the class picker (or type !bot tank, !bot dps or !bot healer). Dismiss, or !bots off, sends them away.
Who comes
Real class characters close to your level when one is free; otherwise guard companions (a Berserker and Rangers).
Rules
Bots never take EXP, gold, items or loot rolls; everything goes to you and your party. They leave when you leave the dungeon.
Tip
A solo player can now clear party dungeons such as the Ship, Bakda included.
